这是我的SQL代码。我选择了每行的价格,每行的里程碑和ID以加入表格,但是我只有一行的结果。
PHP代码做多个过滤器:
if($i==0)
{
if($fc == "projet")
{
$filtre_bdd .= "AND p.$fc = '$fv' ";
}
else
{
$filtre_bdd .= "AND cible.$fc = '$fv' ";
$i= $i + 2;
}
}
SQL查询:
SELECT cible.prix,a.valeur,a.idroute,cible.id,p.id,
SUM(DISTINCT a.valeur) AS total_avances, /* the milestone sum the unique one */
SUM(a.valeur) AS total_avance, /* the milestone sum of each row */
SUM(cible.prix) AS total_prix /* the price sum */
FROM avances AS a,routes AS cible,projets AS p
WHERE a.idroute = cible.id AND p.id = cible.idprojet $filtre_bdd /* the conditions to join the tables and do the filter */
GROUP BY cible.id, a.idroute
HAVING total_avances <> cible.prix AND cible.prix - total_avances >- 1
现在,如何获得所有这些条件下的价格总计和里程碑总计?目标表包含项目的ID和里程碑的ID。我们必须对每一行进行里程碑总和,并将总和与项目价格进行比较。
最佳答案
尝试使用以下查询:
SELECT DISTINCT cible.prix, a.valeur, a.idroute, cible.id, p.id,
SUM(a.valeur) AS total_avances,
SUM(a.valeur) AS total_avance,
SUM(cible.prix) AS total_prix
FROM avances a INNER JOIN routes ciblE ON a.idroute = cible.id
INNER JOIN projets p ON p.id = cible.idprojet
GROUP BY cible.prix, a.valeur, a.idroute, cible.id, p.id,
HAVING total_avances <> cible.prix AND cible.prix - total_avances >- 1
希望这可以帮到你。
